I was having this problem and converting worked, but can you tell me is there a quick way to convert them all? or do you have to open each one save it to a model and them save as a .duf - rinse, repeat, repeat, repeat, repeat ... :(

note: Due to a limitation in how DAZ Studio handles presets, only material presets which are in DUF format can be directly applied. Any existing material presets must be re-saved in DUF format from the original Victoria 4.

I have been applying all sorts of file formats to Genesis (1) from the day it came out. It's not D|S that's limited is Genesis 2!!
